FEED-WATER HEATER AND PURlFlER.

SPECTPICATION forming part of Letters Patent No. 302,955, dated August5, 1884.

Application filed February 23, 1884. {No model.)

ToaZZ whom it may concern.-

Be it known that I, Fonnvon Sronnn, a

' subject of the English'Government, (but have er and Purifier for Steam-Bilers, of which cupya perpendicular position.

the following is a specification, and that according to my knowledge andbelief the same has not been in public use or on sale in the UnitedStates.

My invention relates to an improvement in feed-water heaters andpurifiers, the object of the same being to provide a device of thischaracter in which the water'filter will be adapted to operate inconjunction with water supplied from a suitable pump; and, further, toprovide means by which the water will be immediately heated to hightemperature by means of steam supplied from the boiler, and by theaction of which the impuritcs of the water are precipitated before thewater passes into the boiler. A further object is to provide a portabledevice of this character which may be readily and conveniently attachedto boiler of ordinary construction; a further object being to provide adevice of this charac;

ter with a swinging or regulable bracket, by means of which the same maybe attached to a boiler either below or above the centerline of theboiler, and yet permit the same to oc- A further objct is to provide adevice of this character which shall be simple and economical inconstruction, and durable and efficient in use; and with these ends inview my invent-ion consists in certain details of construction andcombinations of parts, as will be more fullydescribed, and pointed outin the claims.

In the accompanying drawing, the figure shown is a vertical sectionalview of my improvement.

A represents a cylindrical casing connecting the upper and lowerchambers, B and (3, which are secured thereto in any desired man ner.Thelower chamber is centrally provided on its lower end with ascrew-threaded opening, through which passes the feed-pipe E,

which is secured therein. The feed-pipe E is provided with ascrew-threaded upper end,to

which is secured the cylindrical box or casing F, which is provided withscrew threaded openings, into which are secured the tubes G, which arescrew-threaded upon their lower ends. Thesaid tubes G may be of anydesired number and size, according to the amount of work desired. Theupper ends of the tubes are provided with the downwardly curved flangesH, as shown, for the purpose of allowing the water to flow therefrom inthin and varied streams. The upper ends of the said tubes G open intothe steam space or chamber B. The said chamber Bis provided with the topI, which is secured thereto in any suit ablemanner. The spaces J areformed be tween the tubes G and the casing A, and open into the chambersB and G, the said space extending within a short distance of the bottomof the lower chamber, G, as shown. Thelowcr chamber, 0, is provided nearits upper end with the water-passage K, which connects with the chamberL. To the chamber L is mova bly secured the filter K, which in thisinstance is provided with a suitable flange, O, which rests upon theshoulder}? of the chamber L. The filter K is made of strong wire-clothof sufficient elasticity to lit closely around the inside of the chamberL. The filter is supplied with a coating of sponge upon its inner walls,the whole being re-cnforced by a quantity of charcoal, and secured inposition by means of a perforated metallic cover, R. If desired, thefilter maybe supplied with ahandle, S, for convenience in removing itwhen it is dcsi red to clean or renew its contents. This maybeaccomplished by removing the cover T, which is secured over the chamberL in any desired manner. The chambers 13 and Larc'providcd withscrew-threaded openings, into which are secured the ends of thesteam-induction pipes U and V. These pipes are provided at any part oftheir length with suitable stop-cocks, for the purpose of regulating theflow of steam into the apparatus. The chamber L is provided above theshoulder P with a screw-threaded opening, into which is secured thewatcr-eduction pipe Y,

. time by opening the cock AC which is inclined downwardly and connectswith the 'boiler, and by means of which the same is supplied with water.

A suitable water-gage, Z, is secured in the position shown connectingwith the spaces J for the purpose of determining at successive strokesof the pump whether or not thewater is passing freely to the boiler. Thelower chamber, 0, is provided with the blow-off pipe and cook A.

For the purpose of providing an adjusting device to connect thefeed-heater to the boiler,

,I provide the side frame, B, of the chamber 0 with an arm, 0, which isformed integral there with or secured thereto in any desired manner. Thearm is provided with a hole through which passes the thumb-screw D. Tothe arm is pivotally secured an adjustable bracket, E, formed, as shown,and provided with the elongated slot F, by means of which the bracketmay be caused to assume any desired position.

Having described the construction of my apparatus, its operation is asfollows: The steam-pipes U and V are opened and the steam issues fromthe boiler and immediately fills all available space in the apparatus.The water is then forced into the tubes G, through the feed-pipe E, and,coming into contact with the live steam, is heated to a hightemperature. The water ascends upward through the tubes, and,overflowing the same, runs over and into the spaces J, and, descendingthe same, runs out at the lower ends into the chamber 0, and fillingwhich, it flows into the water-passage K, and through the chamber L intothe filter K,and from thence into the induction-pipe Y, which leads tothe boiler. The continuous action of the steam upon the waterprecipitates the matter, sediments, and other impurities, which fallthrough the spaces J into the chamber G, from whence it may be removedat any By the above means the boiler is supplied with water possessingan equal temperature to that already in the boiler, thus overcoming thedanger of sudden contraction and expansion of the plates, and otherprobable dangers likely to result from the sudden introduction of coldor partially-heated water into the boiler.

It is evident that slight changes in the construction and relativearrangement of the several parts of my invention might be resorted towithout departing from the spirit of myinvention, and hence I would haveit understood that I do not confine myself to the exact constructionshown and described, but consider myself at liberty to make such changesand alterations as fairly fall within the spirit and scope of myinvention.
